The difference between the bond and dissociation energy is due to the fact that molecules are never at the minimum of the potential curve. The Heisenberg principle prohibits the energy and time to be known at the same time, so the molecules are never at the minimum of curve, thus always having some vibrational energy equal to the difference between these two energies. When the calculated energy of bond energy for the ground state is calculated in kJ/mol, the obtained value is 124 kJ/mol which compares quite well with the literature value of 150kJ/mol. The dissociation energy in literature is 152 kJ/mol and calculated one was 126 kJ/mol which also compares well to the experimental spectrum....
